The component of formula electronic equipment, and it is not intended as the complete diagram of the various assemblies needed for portable electronic device.Therefore,
Portable electronic device may include the various other components being not shown in Fig. 3, or may include two or more components
Combination, or specific components can be divided into two or more independent assemblies, and be still within the scope of the present invention it
It is interior.
Fig. 4 is the flow chart of the embodiment of the method for the present invention.As discussed above, equipment can receive defeated from sensor
Enter signal 430, data-signal 432 is received from the processor of equipment and/or receives external data signal 434 from external source.Example
It is provided above.Each exemplary further example includes receiving input signal from one or more sensor, and input passes
Sensor can be the microphone of the echo state for determining environment.Consider in the available such as time of day of device handler
Certain data can help to distinguish between daylight interference and artificial incandescence interference, both have high IR contents but
It is different in terms of intensity and spectrum, and correspondingly such interference filtering can be adjusted.In time of day
Top increase visible light sensor and can further assist in the type of existing artificial light, that is, determine that it is IR contents
The low fluorescence of high incandescence or IR contents.In the latter case, it works in infra-red range for reducing or eliminating
The filter for the noise that proximity sensor is received can be deactivated or substantially loosen, and therefore can reduce energy consumption or make it
Range is promoted.In order to receive external data signal from external source, the environment and/or feelings with equipment can be downloaded from remote server
The relevant information in border.There are many other examples, and it should be understood that, it is used for receiving input signal from sensor, from setting
Standby processor receives data-signal and/or receives range of any way all in the discussion of external data signal from external source
Within.
By will the input signal 436 from sensor, the data-signal 438 from device handler and/or from outer
The external data signal 440 in portion source be associated with to equipment environment and/or situation assess comprising ambient light
And/or including all values 442 in association process, to generate characteristic value 444.Each type of adjusting can be directed to generate not
Same characteristic value 444, for pulse power to influence ranges of sensors, pulse frequency, the sensor input for weakening interference
The noise filtering of signal and the frequency spectrum of proximity sensor, or the characteristic value 444 of combination can be generated.For illustrated flow chart
It is brief, there has been provided the situation of the characteristic value 444 individually generated.Characteristic value can be any suitable unit either list
Pure number.
In order to determine equipment 101 (see Fig. 1) proximity sensor one or more patterns, can will be one or more special
Value indicative is compared 446 with look-up table, and the look-up table can be stored in the memory 305 of equipment 101 or can be remote
Journey accesses.Algorithm can be combined or be used alone to processing one or more features value to select equipment 101 with look-up table
Proximity sensor pattern.
Once having selected the pulse power for influencing ranges of sensors 450, pulse frequency 452, for weakening interference
One or more of the noise filtering 454 of sensor input signal and the frequency spectrum 456 of proximity sensor, so that it may with to close
The pattern of sensor is adjusted.Adjusting may include when being adjusted pulse power to influence to include impulse amplitude and is lasting
Between ranges of sensors 460, pulse frequency is adjusted 462, to the noise filtering of sensor input signal be adjusted with
Weaken interference 464 and 466 are adjusted to the frequency spectrum or frequency range of proximity sensor.Since proximity sensor can be
Hypersensitization, so carrying out the function that such adjusting can cause its optimal and enabling it to consumption minimum.
